Question about JG M4-S System (Enhanced Version)

I wanted to put a 180mm silencer on my JG M4-S and a 550mm barrel for more accuracy and range. I was wondering if the gun's internals are powerful enough to push a bb through that barrel because some people say that I may need a stronger spring, etc. All the internals are stock.

i strongly recommend installing the proper cylinder to go with that length barrel. not doing so could cause issues regardless of the spring. additionally, to keep costs down and get the same result (if not much better), keep the same length inner barrel, purchase that length with a tightbore 6.03 diameter, and upgrade your hop up bucking and nub (recommend the madbull red bucking package that comes with a nub.

ive tried using a 6.01 an echo 1 blue bucking or madbull blue and a pcs spacer/shredders concave spacer and the results are amazing
